Synthesis and Application of Polyhedral Oligomeric Silsesquioxane

Polyhedral oligomeric silsesquioxane(POSS)is a new-type silicone hybrid material and used for heat-resistant and flame retardant materials and enhanced polymer materials with wider applications.The synthese,in- fluencing factors,propertyies and applications of four kinds of POSS containing phenyl,amino,epoxy and methyl groups are discussed respectively in this article.
